Estimating the Field Capacity of Farm Machines | Ag ...
This capacity is called the machine's material capacity (MC), expressed as bushels per hour or tons per hour. It is the product of the machine's EFC and the average yield of crop per acre, and can be calculated from equation (5). (5) MC(bu or tons/hr) = EFC(A/hr) x crop yield (bu or tons/A) For example, a baler with an EFC of 5 A/hr working in a field yielding 3 tons of hay per acre .
